I think the point was that, in the course of getting the system set
up and configured properly, there were some things loaded for use
while configuring that are no longer needed in production; and there
may also have been some things loaded that turned out never to
have actually been needed (but that wasn't apparent when they were
installed).  In principle, a reinstall might manage to avoid the
latter group; it's less clear that it would avoid the former group.
